"The clock at LN2 fill system is off by about 25 minutes (filling comes later than set at the control unit.)"

Yes, This is how it always was.

"Filling of G7 was stopped by "emergency sensor" after about 15 minutes of filling. Likely the temp sensor at the LN2 overflow pipe of G7 should be changed."

You can put this on a different line of the fill system....

We observed 6 pm LN2 filling of both clovers on Monday Nov 5th.

D4 went full within reasonable time of below 10 minutes.

Filling of G7 was stopped by "emergency sensor" after about 15 minutes of filling.

Likely the temp sensor at the LN2 overflow pipe of G7 should be changed.

The clock at LN2 fill system is off by about 25 minutes (filling comes later than set at the control unit.)

With detectors still on the floor we check signals and found
that D4 gives no signal with PA power.  Two power supplies/cables were checked.
The detector was still working just before Jungclaus experiment. In July it was working.

Temperature monitors OK: 76-80 units

We mount both CLovers in position and make all connections.


We apply HV and check the resolution of G7.

Comment: V2A8C9 contains now the 10Hz clock signal coming from

It will be there even if we inhibit the pulser signals to the preamps

the gate generator produces double peaks from the 100Hz clock

Comment:
Tube 121 is noisier than the others (see fig).

Issue:
all the channels connected to PA3 and PA4 
have twice the number of counts than the remaining channels (!?).
Actually the pulser counts.

Solution:
This channels are from UPC tubes and are connected to pulser PB-5.
We found that the threshold of external trigger was set to 1V
instead to 1.8V as before and this was producing a double pulse (see photo)
like triggering on the fall and rise of the trigger pulse.

We do not understand this: the signal has +2.2V and no apparent ripple (!????).

- Start DACQ computer: OK!
- Create directory: /data/1810Preparation/
- Copy last configuration RIBF139 file:  171119_1126_Conf_BrikenFullYSO.xlsx
- Return PB-5 pulser into crate and set parameters
- Star all crates: OK!
- Start DACQ: OK!
- Rename configuration file and edit to eliminate YSO related parameters
  New Config file: 181016_Conf_BrikenFull.xlsx
- Start 3He tube HV: power the ethernet hub, power the pixie PC,
  edit the hvmon.conf file (only tubes active), run hvmon: OK!
- We realized that current and voltage of VME crate 1 was oscillating.
  We pulled out V1A7 (not used) and it became stable: seems that we are at the limit of 
  power supply: OK!
- We put the 252Cf source in and check gain match:
  only (the gain of) three tubes moved slightly since the last run (one year ago)!
  He006, He134, He135 -> new calibration: OK!
- We move SIS3820 clock from internal to external frequency:
  Setup UK Tektronix clock: 25MHz, square signal, 800mVpp, -400mV offset
  Plug in Lupo module (VME1 crate): OK!


ISSUE: the current placement of the table supporting the MUSIC chamber
is too close to the VME1 crate and one of the modules (V1A4) 
cannot be extracted in case of failure. However V1A7 is unused
in this run and can be used as replacement.

The PB-5 Pulse generator labeled "Pulser 2" and the 428F Linear Fan in-out labeled "Clover G7" from BRIKEN NIM crate have to be returned to the RIBF electronics pool because the 
borrowing time is expired.

For the Pulser 2, the external trigger input and pulse output cables were labeled before removing the module.

The Linear Fan in-out was replaced with a new module (same version 428F), which can be used for a long time. The position of the input and output cables in the module were kept 
unchanged.

Here is a doc with an estimate of the statistical uncertainty P1n and P2n as a function of the number of implant-beta correlations for future experiments.

This will hopefully be useful for the new PAC proposals as an estimate for the time needed to measure a certain precision.

If there are any questions please feel free to email me (Charlie Rasco).

I roughly (~10%) checked the efficiency for 4 of the peaks from  171025_1222_1355_152EuCloverCal.root.

I checked the peaks at 122, 245, 344, and 1408. The indication is an efficiency of 6.9,  9,   9,8, and 2.6 % for these gamma rays repectively.

Previously the efficiency was 11.1, 7.1, 5.3, and 1.6% . This indicates a reduction in efficiency below ~200 keV (because of YSO) and otherwise there is an increase in efficiency from 40% at 245 keV and up to 65% at 1480 keV.

A more complete analysis will come later.

G7 pulser weird behavior

Pulser removed from G7Red & G7Green

Background measurement
Start: 01:44
Run:   000
File:  171026_0144_bck_000.dlt
Stop:  

The presently used detector has 48x48x5 mm3 YSO array with 1x1mm2 segments. They are separated with ESR.  We use H8500 pspmt and 2 mm quartz diffuser with rough edges. Coupling is done with sylgard.  Anger logic uses a conventional resistive network with 1kohm and we have 4 position signals and dynode.  The position signals (xa,xb,ya,yb) are split in Low gain branch connected directly to 5V range input in Struck and High gain branch, which uses Phillips fast amplifier to boost the gain. The use of the amplifiers enables to operate the detector at low PSPMT gain and should give us a chance to work with the strong light produced by the implant.  The implant signals were simulated using blue diode and a pulse generator. We observed significant drift of the position for very large pulses, but this was for now attributed to be the pulse shape effect due to the use of the diode and reltively slow pulser.

YSO for now should run at -700 V.  The maximum operating voltage is 1200V and should not be exceeded. At 1200 V the ions induced signals may saturate our electronics.

Tuesday evening:

Detector remounted in the pedestal and aligned with WASABI with 1mm+1.5mm spacers. The pedestal is 25.8 mm tall and the box is 60 mm tall.  We checked also the orientation of the spectra and chose AIDA convention (look upstream). With this pedestal the front of the box is centered with the back of the clover leaf.

Wednestay morning:

I opened the detector and rewrapped it with new teflon tape. I noticed a small piece if sylgard peeled off, which may explain why the we had some edge effect yesterday. The detector was remounted on the new pedestal which will allow it to be positioned at the center of the clover.  The signals looked OK on the oscilloscope.

(compare figure of BRIKEN spectrum in attachment with similar
figures of previous runs)
2. The 252 Cf source used immediately before has activated
something as can be deduced from the change of rate

see picture below. The effective half-life of the activation is
T1/2=71.8min

Also the threshold of Clover detectors was slightly increased.

Configuration of BRIKEN DACQ hardware:
Detector->VME->ADC->Channel

New configuration:
Ancillaries are moved to crate #2: V2A8 (SIS3316)
YSO is on crate #1: V1A7 (SIS3316)
V2A4 (SIS3302) failed and was replaced wit spare unit (Chan #5 missing)

Ancillaries are reduced to F11 Plastic (Right and Left, Direct and Attenuated)
and AIDA Plastic veto. The 10Hz pulser signal is also fed to this ADC (Dead Time Pulser).

YSO provides 5 signals: xa, xb, ya, yb and dynode.
Each signal is splitted. One branch of xa,xb,ya,yb is amplified
the other goes directly (but it might be eventually attenuated).

High voltage control: All High voltage 3He and HPGe can now be set via a configuration file called hvmon.conf and a program called hvmon. hvmon also watches the temperature of the HPGe via the RTD outputs and sets trip and other safety settings.

The important locations are as follows:

• Path for conf file: /home/pixie16/DAQ_BRIKEN/include/hvmon.conf

• Path for temperature monitor: /home/pixie16/DAQ_BRIKEN/kelvin/kelvin-u3

• Path for temperature logging: /home/pixie16/DAQ_BRIKEN/kelvin/kelvin-log

• Path for temperature log control: /home/pixie16/DAQ_BRIKEN/kelvin/kelvin-read

• Path for hvmon: /home/pixie16/DAQ_BRIKEN/hv-mpod/hvmon

• Path for hvmon control: /home/pixie16/DAQ_BRIKEN/hv-mpod/hvmon-read

This is also the order in which the programs should be run at first.

If the kelvin temperature monitoring programs are already running ('ps -A | grep kelvin' to check) and you wish to change the settings:

1. Adjust hvmon.conf

2. stop 'hvmon' with ctrl+c

3. rerun by './hvmon' (also 'up + Enter')

If kelvin is not running, in a separate window or screen

1. cd /home/pixie16/DAQ_BRIKEN/kelvin/

2. ./kelvin-u3 &

3. ./kelvin-log &

Then proceed with the above.

This is also the order in which the programs should be run at first. 

If the kelvin programs are already running ('ps -A | grep kelvin' to check) and you wish to change the settings:

2 OPTIONS!

Option 1:
Adjust channels that have previously been declared by using

./hvmon-read

16

and follow on screen instructions. If channels have not been declared previously in hvmon.conf → proceed to option 2.

Option 2:

1. Adjust hvmon.conf

2. stop 'hvmon' with ctrl+c or by ‘100’ at hvmon-read

3. rerun by './hvmon &' (also 'up + Enter')

The example below turns on ALL detectors PA (Pre-amps1-10), D4/G7 HPGe (KRGB, Black, Red, Green, Blue), and YSO/Gari. This example sets all detectors voltage,ramp up/down speed and status (0/1 = Off/On respectively). IMPORTANT! Ramp speed goes card by card.

UPDATE!!

3He Preamps now run up and down by a small ramp for the first 50V hardcoded into hvmon via the ‘PA’ keyword. This avoids the reset fault.

=================================================

Everything below type = -1 is treated as a comment

type = 0 => MPOD HV modules => accessed thru snmp

type = 1 => CAEN x527 HV modules => accessed thru CAENHVwrapper

With MPOD one can use IP address and channel numbers based on slot occupation
PA(1-4) are differential and PA(5-10) are unipolar.

In the program hvmon-read ‘Off’ always means ramp down and then turn off. The PA's like to hold on to voltage (~10-50V) and may cause a fault at ramp down and need reset. This should be Fixed with two stage ramping.

Warning!!: It has also been realized that mpod changes ramp up to be equal to ramp down. These parameters can be made equal for transparency.

To reset after fault use:

./hvmon-read

18 (or 5 then 18)

In case of power loss or other failure hit to do an emergency shutdown of the voltages.

./hvmon-read

5

The online seems to be missing some slides, but the pdf has all of the slides.

Green and Red channels were repaired by crimping and securing the grounding of the cables and fixing the cables securely to the table. 

All problems during the repair process were visible on the scope. See example attatched. 

Calibration is as:

Edit(10-21): NB realized calibration was not performed on the raw spectra, but on the previously calibrated ones. These values are wrong!

A scaning with 252Cf along the Z-axis of the neutron detector is carried out. The setup is similar to the scaning carried out in October 2016.

Observations:

- Clovers are put inside the detector without voltage.

- AIDA detector is out of the moderator.

- Position in Z is given with respect to the moderator side opposite to AIDA.

- The shielding for in-beam neutrons is mounted. It corresponds to HDPE 2.5cm + 1mm Cd + 20cm HDPE. The distance moderator to shieldind is 34.6mm

- There are two additional neutron sources in the Hall, aprox 10m from the detector. One 241AmBe (30mC) and 244Cm/O13 (500mC). Both sources produce an increase of the neutron background up to approx1n/s (x10 higher).

New configuration file of BRIKEN
Changes of 26th-May-2017
Previous config file 24th-May-2017

After the 152Eu calibration, the threshold of 
>> V2A7C4 was increased from 20 to 30. 
>> V2A7C6 was increased from 30 to 40. 

AIDA veto plastic (40cm after the stack of DSSD) and 
the silicon detector (shielding hole) were calibrated 
with the Compton edge of 137Cs (891keV).

We started the synchronization monitoring programs to check that
it is OK as can be seen in the figure below

We are using the same scheme used during Ahn parasitic run,
namely the synchronization check signal is the BigRIPS trigger
signal send by them to us (AIDA, BRIKEN).

The monitorization procedure is different from the one used
in 2016. The description to lauch the processes is described
here below and in the attached PDF.

***********

To Launch the processes:

Open 4 terminals:

Terminal 1 (DataSink) type:

>ssh aida@d05

>cd /home/aida/DataPackage/DataSink/Linux64

>DataSink -i 3

Terminal 2 (SynCheck) type:

>ssh aida@d05

>cd /home/aida/SyncCheck

>./SynCheck

Terminal 3 (BigRIPS Data Relay) type:

>ssh aida@d05

>cd /home/aida/ribfts/ribftssender

>./ribftssender_mar17ca debug

(specific for current 40Ca parasitic run because we are not sending
a pulse signal to  BigRIPS as trigger but receiving triggers from
BigRIPS to create the pulses)

Terminal 4 (AIDA Data Relay) type:

>npg@aidas1
>DataRelayFilter -n 10.32.0.12 -p 10307 -I 2

"-I 2" selects ID 2 as the one for the AIDA data stream, 
which must correspond to the one expected by the DataSink in the d05 PC.
The programming transmitting the data from AIDA to the DataSink includes an 
intermediate filtering step. This selects only correlation scalers from one 
module (and possibly ADC values from one channel in that module).

Gasific MainWindow (Briken Data Relay):

   In the DAQ Control tab: Click "Start Sync Monitoring" button.

   In the pop up window set server ip and port (ip:10.32.0.12, port:10305)

By default this perform a check on the differences RIBF-BRIKEN and AIDA-BRIKEN.

In case that BRIKEN is not running, the option "SynCheck -M 1" check the differences 
AIDA-RIBF and BRIKEN-RIBF, while "SynCheck -M 2" checks RIBF-AIDA and BRIKEN-AIDA

To synchronize:

   In the Gasific MainWindow, DAQ Control tab: Click "Send Sync Pulse" button

We realized that the time stamp was not reset.

Both clover detectors were moved. They are in a symmetrical position. The end on the clover nose is of the order
of 3-4 mm from the AIDA tunnel.

See sketch of CLOVERS with respect to beam.

See photos of the insertion distance of
both CLOVERS

We have noticed that D4 is not in its right position. That explains the different number of counts in the
detectors. 
Probably of the order of 3 cm away from its nominal place.
The position of the other detector should be also checked.
Efficiency calibrations need to be repeated

Comment: we noticed that the two clovers had different statistics for the 1332 peak. To be checked why
(source not in place ?)
The pulser shows similar counts, so the reason can not be deadtime

Answer: the D4 was not in its right position !!!!, efficiency calibrations have to be repeated :-(

We started the measurement of the source when the N2 filling started. Just to  check if there are funny things
related to the filling.

Ps. See that the pulser generates peaks in the region 250-270 keV (to avoid people to invent new levels (and
gammas) populated 
in the beta decay of 133Ba). 

We connect the pulser to both CLOVERs

G7: It looks OK except for the G7-Green as before
(there pulser peak in the spectrum)

D4: the pulser peak appears at very low energies (200-600keV)
there seems to be a problem with pulser processing in the preamplifiers.
Should we still use it? We remove for the moment.


152Eu source calibration.

We put the 152Eu source at the center (on the cardboard)
and check de energy calibration. For most of the crystals
the calibration from March was pretty good except for D4-Red
that the gain changed by a factor 1/2 and D4-blue that changed by 2 (!?)

We redo the calibration:
G7: the resolution at 1.4MeV is 2.7keV
D4: the resolution at 1.4MeV is 3.9keV

OBSERVATIONS: PPAC discharges every ~10min (got better)

The BigRIPS settings are all called "36Ne setting" but the night shift labels these runs in the BRIKEN DAQ as
"37Na". We are not sure why we label it with 37Na, we think this should be consistently named 36Ne like the
BigRIPS settings. (For sure the strongest component in the beam might be 37Na. In the 39Na settings before it
was 40Mg and we labelled it 40Mg...)

Observations:
- We should increase the gain of F11 plastic (now a bit to small)
say by a factor of 2. Calibration is probably wrong!?

Start of parasitic Ca beam
(main experiment "New isotope search", Ahn et al.)

New directory: /data/1703Ahn/

Configuration file: 170329_Conf_BrikenFull.xlsx

New calibration of F11 plastic

We decided to have both a low gain and a high gain 
for F11 plastic dividing the signal from the TFA 
with a "T" and using in one branch a 20db attenuator (reduction by 10)
and sending to two different DACQ channels.
The gain of the TFA was also reduced to x2

V1A7C3: F11_PL_R (Low gain: ~60MeV)
V1A7C4: F11_PL_L
V1A7C5: F11_PL_R_HG (High gain: ~600MeV)

>DataRelayFilter -n 10.32.0.12 -p 10307 -I 2

"-I 2" selects ID 2 as the one for the AIDA data stream, 
which must correspond to the one expected by the DataSink in the d05 PC.
The programming transmitting the data from AIDA to the DataSink includes an 
intermediate filtering step. This selects only correlation scalers from one 
module (and possibly ADC values from one channel in that module).

Gasific MainWindow (Briken Data Relay):

   In the DAQ Control tab: Click "Start Sync Monitoring" button.

   In the pop up window set server ip and port (ip:10.32.0.12, port:10305)

By default this perform a check on the differences RIBF-BRIKEN and AIDA-BRIKEN.

In case that BRIKEN is not running, the option "SynCheck -M 1" check the differences 
AIDA-RIBF and BRIKEN-RIBF, while "SynCheck -M 2" checks RIBF-AIDA and BRIKEN-AIDA

To synchronize:

   In the Gasific MainWindow, DAQ Control tab: Click "Send Sync Pulse" button

Today, Gabor and I discussed with Nathan from ORNL about the biasing system used for Ge, 3He, Plastic, and others.  Phong is also a bit familiar with the system (edit also 
Shintaro 
Go).  While there 
is supposed to be a manual, Gabor and I did not find it.
In case of trouble: contact Nathan Brewer Gmail: Brewer.nathant@gmail.com Skype: nathan.t.brewer

Log in to high voltage PC:

$ ssh -Y pixie16@10.32.6.161
passwd: ************

For HV readout, run firefox in the background

$ firefox &

You can probably check the history or restore pages, but it should be pointed
at 192.168.13.239

It updates automatically every several seconds.  Unless the HV monitor is
running, it may show nothing...

For temperatures:

$ cd ~/DAQ_1/kelvin
$ ./kelvin-read

(there are options to kill all temperatures)

For applying existing HVs (BE CAREFUL!)

$ cd ~/DAQ_1/hv-mpod
$ ./hvmon

If you want to change the voltages (up or down) kill this with Ctrl+C

To alter bias values or change which ones are on, you can edit the file:

$ ~/DAQ_1/include/hvmon.conf

Once the file is saved, restart hvmon.

We are running the above in a GNU screen session, with firefox on one computer.  It has a note taped to it.  Please don't use this computer for other purposes unless necessary!  
Let me note that the PC we log in through has essentially no .screenrc file so you can barely understand you are actually using screen.  If you are not very familiar with 
screen, better not to touch it.  I will put a better .screenrc later (but I also don't want to change the setup now).

Ge voltage application

LN2 filling was done yesterday before lunch

D is the beam left side Ge
	MPOD	name
	U300	D4K
	U301	D4R
	U302	D4G
	U303	D4B

83.7 K, with 300 V

G is the beam right side Ge
	MPOD 	name
	U304	G7K
	U305	G7R
	U306	G7G
	U307	G7B

79.6 K with 250 V (except G7R at 300 V)

All analog signals are seen in the oscilloscope with reasonable behavior

28 Mar 2017 15:56:03 

Ramp up all Ge clovers.

D at 3000 V for all

G at 2500 V for all (except G7R is 3000)

28 Mar 2017 16:26:39 

Biases are all applied (maybe several minutes earlier)

D4 temp 83.7 K
G7 temp 79.6 K

28 Mar 2017 17:51:09 

Now we ramp up 3He and plastics.  We keep the Ge on during this time.

D4 83.7 K
G7 79.6 K

Everything looks good!

Stopping power calculation (SRIM):

100 MeV/A 40Mg: S=102*0.7129= 72.7 MeV/mm 
(Later: according LISE simulations energy loss of 40Mg  is 88MeV)

What is the energy loss of the "light" particles?

We applied a bias voltage of 100 V to the dE detector

Current read = 0.660 uA

compare with https://elog.ph.ed.ac.uk/BRIKEN/190.  it is slighly lower.

Short background run: 170323_1841_Background.root.
Neutron spectrum looks OK (see attached graph)
All the tubes look Ok.

We remove partially the floor rails of EURICA 
to proof that it is possible to move BRIKEN + AIDA.

See attached photographs of the present status.
This will allow eventually to move both detectors by about
1 meter to have a better focus at the implantation position.
This movement could be done with a minimum of cable disconnection
using the wheels of both support tables.

We started the preparation of 2017 campaign

Check of calibrations and rates for neutron detectors with Conf File 161107Conf_BrikenFull.xlsx

Measurement 161122_2208_003.root has been used to check the calibrations and counting rates in the BRIKEN
detector. Condition of the measurement:
252Cf at 22.5cm from moderator, opposite sede from AIDA

RESULTS

Calibrations factors:
Calibrations of the neutron detectors are reasonable in the current conditions. A check detector by detector
(see attached file) shows that the full peak for most of the counters is around 764keV. Only 3 counters are
shifted more than 10keV:
He134	741.901
He135	750.312
He140	748.587	

The impact on the counting rates would not be serious.

Counting rates (n/pulser):
#########################################
Total neutron rate:	1516.28
#########################################
	BY RING:
#########################################
R1	359.057
R2	222.997
R3	386.299
R4	253.833
R5	143.434
R6	90.6357
R7	60.025

The total current counting rate is lower than rate obtained in Oct 12th (total 1550.91 n/pulser). The difference
is due mainly to a decrease in the counting rates for rings 1 to 4.

We've turned on the High Voltage for the D4 Clover up to ~ 1.5 kV. 
There is no current (0.0 uA) observed in all the channels (crystals) of this clover while the High Voltage is
turning up.
We have turned down the HV after that.
We've checked that the NIM crate power supply for the preamp is On and the HV and peamplifier connections for
this Clover are Ok.

These are the files used to create and visualize the hit patterns of the BRIKEN detector.

There are three files needed plus one input data file. The three files are "HybridBRIKENPhysicalHistogram.hpp", "HybridBRIKENPhysicalHistogram.cpp", and "HybryidBRIKEN_Tube_Info_1.txt". These files are attached to this eLog entry.

In order to run this type in a terminal

root -l HybidBRIKENPhysicalHistogram.cpp+

The plus is important, it tells ROOT to compile this with the gcc compiler and then run that compiled version of the code. It runs slow, if at all, in the ROOT C++ interpreter CINT.

The code has been tested with ROOT v5.32 and v5.34, not version 6.

At the bottom of the HybidBRIKENPhysicalHistogram.cpp file is the "main program". In it you can set the input data file, which should be a BRIKEN online root output file, and the 3He energy cuts. It is easiest if all the files are in the same folder. If there are any questions please feel free to email B. Charles (Charlie) Rasco.

At least during the timeframe in between ~ 21:30 (11/08) - 23:30 (11/09) (161108_2323_717273Ni.root) we see that the silicon dE have a very low counting rate. ~1Hz when the first AIDA detector sees ~600 Hz and a cumulative ~2kHz. The energy range in the dE stops at ~10MeV.

Edit: It appears the Si dE were removed. Some signals are still in the spectra.

71,72,73Ni  run

We started at approximately 21:00, only online, not writing on tape. 

The lead is still in the way. We removed the degrader (fully) and the effect is a 5 % reduction of the neutron flux 
(determined using the rate of the rateF11/rateBRIKEN  before and after the change).

Some spectra show spikes or do not look normal. This should be checked.

Look at BRIKEN, Ring4, Ring5, Ring6, Ring7, D4, G7, Clovers, 
Rate1, Rate2, Rate3, etc.

Reset time stamp: 21.00, 8th-nov.

Probably there was a problem with the clock from AIDA related to the LN2 filling.
So to recover, we need to stop acq (only stop acquisition in DACQ control), 
send to hard (send parameters again) and once all the parameters were sent, 
Send Sync pulse.

We will start to use the internal RIKEN ELOG
It is not clear that we can keep the present ELOG also updated

Sequence of settings:
1) No target at F7 and Empty target at F11 (up to t=1E6ms)
2) No target at F7 and C-6mm target at F11 (up to t=5.1E6ms)

F11_left (V1A7C4): 0.01155

AIDA plastic (veto) and Si de calibration

For the calibration the Compton edge of the spectrum seen in the detectors was used.
There is a large uncertainty in that determination, since the spectra are not so clear in terms of shape.

For the spectra V1A7C13_EFIR (Si de, top) the channel position is 12900 units

For the spectra V1A7C14_EFIR (Si de, bottom) the channel position is 12950 units

For the spectra V1A7C9_EFIR (AIDA plastic) the channel position is 10425 units

These corresponds to the following calibration factors using 0.9 MeV as the Compton energy from Co source:

V1A7C13_EFIR (Si de, top): 6.976744E-5
V1A7C14_EFIR (Si de, bottom): 6.949807E-5

62Ni on 6 mm C target between MUSICs

The background before was 0.36 neutrons/s
Now it is around 10 n/s
With 3100 counts/s at F3 we have of the order of 25 neutrons/s
There is an slightly higher than 10 factor between the rate of 
the plastic top and bottom (13 cts/s vs 1ct/s).
Rate at F11 (plastic) 900 cts/s.

We start a proper measurement with DLT

They will measure with 6mm C target (between MUSICS) for

Figure with F11 spectra: Right (red), Left (blue)

Figure with time correlation between F11 and BRIKEN
The number of correlations (integrated spectrum minus flat background)
is 73063 very close the number of detected neutrons 73899
The difference 833 agrees well with the expected number of background
neutrons. That is: for every neutron detected in BRIKEN there was an 
ion passing through F11 (!?).
There is a funny double structure in the first 20 microsec.
94% of the neutrons are detected within 200microsec

Figure with the spectra of Veto plastics Top (red) and
bottom (blue). There are 7.5 times more counts in T than in B.
One can see in the Top peaks at 3MeV and 12MeV 
(corrected from 6 and 25 MeV: wrong calibration!!)
and show signals up to very high energy (GeV)

Figure with the time correlation between Veto Plastics and BRIKEN
Top (red) Bottom (blue). There is a time correlation with Top veto plastic
for 15% of the neutrons in BRIKEN (11440). There  are 18 times less 
correlations with the Bottom plastic. 
WARNING: The correlation was done for signals above "20MeV"
in the V_PL_T spectra i.e. only including the second bump"

Some info on ancillary detector signals

Plastic veto detectors (Top and Botomm):
The dynode signal of the PMT is passed through an
ORTEC 474 TFA amplifier before going to the DACQ
TFA: Gain=6 x min(~x2), Tint=200ns,Tdif=100ns, NonInvert
DACQ channels: Top: V1A7C1, Bottom: V1A7C2
Photo of the signals of both detectors attached 
with 60Co source (with gain changed to 20 x max(~x12.5))
200ns wide 70mV high signal

With this info a rough calibration was established:
for the 2V range an ADC unit is 2000mV/16384=0.122mV
the 70mV (~1MeV) correspond to 574 ADC units which
with the change of gain 6*2/20/12.5=0.048
become 27.6 ADC units. We checked with Gasific
that roughly 1 ADC unit corresponds to 2 EFIR units
thus the calibration is 1/2/27.6=0.018 MeV/unit
NOTE: the calibration in online spectra taken
before noon Sunday 6 was wrong by a factor 2
too large!!!!


Si detector (Top and Bottom halves):
Signal from preamplifier in the low gain mode for the measurement:
we see nothing on the scope with 60Co source. In the high gain mode
we saw the other day a negative 6microsec wide 1mV high
signal with a 60Co.

AIDA plastic veto:
The signal from the PMT is going through a CAEN 
shaping amplifier. The signal has a bipolar shape
with a rise time of 500ns a total width of 2microsec
and a height of 100mV (60Co)

F11 ToF plastic (Left and Right):
The signals are processed  in the same way that the
plastic veto detector with TFA using the same settings.
Polarity of the signal unknown.
Currently we see no signal seems its not connected.
We found later that the NIM crate where the 
TFA  were sitting was not on!
We just made a  calibration with beam particles
LISE was used to estimate an energy loss of 65 MeV for the ions.

We looked at the overnight background run (161105_0935_BackgroundOvernight.root), There are gamma-peaks that could be related to neutron inerastic scattering. We identified 565, 596, 608 and 69 keV. They might be related to the effect of neutrons. If this is the correct assignment, this would mean at least some of the neutrons are not thermal when they interact with the germanium. 

There was also significant drift in the Ge gain (seen on the pulser) this may effect the shape of these peaks. 

Some gain drift was also seen on He preamps during this run. The cause is yet to be determined. It is also yet to be determined if these gain shifts are correlated. 

Measurement overnight

Start: around 1:00
Stop: 9:35
File: 161105_0935_BackgroundOvernight.root

The background level after removing the 252Cf source
from the hall dropped to 0.4n/s.

During the night there were neutron rates up to 120 n/s (see figure)

There is a huge spike in the rates which coincides with the time of 
LN2 filling. One can see spike in several spectra (not in all)
One can see also a structure superposed

The rate per rings is also shown. The outer rings see
a higher rate.

Also shown is the comparison of He107 one  (blue) of the outer ORNL2 tubes
with He084 one (red) of the inner ORLN2. The increase in count rate
is about 30%. 

Also shown is the comparison of two external tubes on the top and the bottom:
He107 (blue) and He137 (red), ORNL2 tubes.  There is no increase in count rate.

Also shown is the comparison of a tube above the lead shielding He028 (blue)
and behind the lead shielding He048 (red), UPC tubes. There is no difference.

There is also  comparison between the rate in the CLOVERS and BRIKEN.
Without beam the rate in the Clovers is around  100 g/s against 0.4 n/s in BRIKEN
At the maximum both rates are similar around 130 c/s.

There is also a plot of the gamma-neutron correlation.
We see that there are neutrons which are detected before
the gammas. A possible explanation several neutrons are produced
one is detected first the second later produces a gamma.

Some photos of the elements in the last part of the beam line
during Takechi run.

After the chamber that includes the F11 plastic detector
there are 2 GSI-MUSIC chambers.

In between the MUSIC chambers there is a sample changer 
with 2 Carbon targets of 6mm and 3mm thickness and also
an empty position.

After the 2nd MUSIC there is a plastic detector for testing 
(could be removed at any time)

Afterwards there is the degrader mounted on a separate table.
In the same table there is a 10cm thick lead wall
to protect AIDA during Takechi run.

Mounted on the shielding are from the beam side the top and bottom 
plastic veto detectors.

On the back side the Si detector is mounted.

The hole in the shielding is covered with
a 2cm thick Al plate to protect AIDA during Takechi run. 

Behind AIDA there is a thin plastic detector
to veto the passing through particles.

Beam tuning in BigRIPS

At 19:00 access to Exp. Area was closed and the tuning
of BigRips started.

Unfortunately the 252Cf was left on the table close
to the stairs and cannot be removed until 23:00.

We did a background measurement
Start: 19:00
Stop: 22:18

File: 161104_2218_BeamTuning.root

In the attached figure 1 one can see a plot of the rate
(neutrons/10s) in the BRIKEN detector during this time
The rate was at high as 150n/s during this period.
We estimate that the influence of the 252Cf source is about 15n/s
(corresponds to the lowest rates)

Also attached are pictures of the Top and Bottom plastic veto detectors
mounted just above and below the hole in the shielding.
Interestingly the bottom sees less counts at high energy
and this could be related to the 10cm lead wall raised
before the degrader to protect AIDA that covers only partially 
the top detector.

Also attached is the neutron spectrum for the different rings superposed.

dE detector is mounted onto the back side of the shielding (attached photo: dE_position.JPG)

The detector consists of 26 strips. In this setup, the detector is devided into 2 parts corresponding to 2 readout channels. Each part consists of 13 strips joint together.

Output signal from a high gain channel of preamplifier with 137Cs source is shown in attachment 137CsTest_ac.JPG.;

The white noise is about 2 mV for high gain mode.

We will switch to low gain mode during the experiment.

* note:there is a 200 mV offset due to the characteristic of the preamplifier (see attachment dc.JPG)

... and sashimi (see photo)

The detectors (BRIKEN tubes, CLOVER, VETO detectors, AIDA) 
are mounted, tested and ready for November commissioning,
except beam detectors a Plastic TOF and a Si detector which
will be attached to the PE shielding.
DACQs (BRIKEN, AIDA) are running. The synchronization monitoring
program which was working in June, for some reason is not functioning
properly now and is being worked on (desirable but not required).
The data merger and near-line analysis programs are being worked on.

Installation of BRIKEN PE shielding for beam
related neutrons

The missing metallic pieces needed to mount
the forward PE shielding finally arrive and
we mount it with help of the crane.

The shielding (4 PE slabs + 1Cd-PE slab) has attached 
the support for VETO detectors on the beam side
and for and additional ancillary detector
a large Si detector on the BRIKEN side.
See attached photos.

The distance between shielding and BRIKEN is 40 cm.

As previously recorded (81), on Thur Oct 13th, A NIM crate failure caused preamp power loss to the HPGe's. While D4 recovered with nominally the same resolution as before. G7 would not recieve power to the preamps without an alarm from the NIM crate.

It was determined that there was a short along the lines of +12V and Ground , -12V and Ground, and between +-12V.

After removing the Red preamp ribbon cable, the remaining channels (K,G,B) were able to be powered on and found to have a nice resolution of near ~2.3 keV for 661 (137Cs).

During the course of testing, the preamp power distribution box (supplied from ORNL) was seen to have a fault in the +12V light and supply. This was seen by placing this supply in a new NIM bin and seeing that it would also not properly supply preamp power to clover D4 (which had recovered fully).

The consistency in this fault is seen as cause to be suspicious of this preamp power supply. It has been replaced by putting two ORTEC TSA's into a seperate NIM bin and using the standard power supply for D4 and G7.

There was no appreciable effect on noise in any other detector.

Change of main power line for MPOD and CLOVER preamp


Because the incident yesterday with the NIM crate,
we try to separate the CLOVER from the rest of 
the equipment.

So we put the MPOD, which powers the CLOVER but also
the 3He tubes and the VETO detectors, and the preamp
power supply in a different line.

We check if this has an impact on the noise in either
CLOVER or 3He tubes.

We measure with the 137Cs-60Co source:
File: 161014_1241_137Cs60Co.root

After inspecting the spectra we conclude that the impact
is not appreciable.

Measurements from Z: -42.5cm to 42.5cm with steps of 2.5cm. 

Gamma source close to ORNL2 tube

In order to investigate the origin of the background
component in ORNL tubes extending up to 200keV
we place a strong 137Cs source (D393) in the hole
of He136 close to the tube.

Control measurement (no source): 161012_1200_bck_control.root
With source: 161012_1229_137CsHe136.root

We observe that the induced signals are in the same energy region
as the 3rd noise component. The increase of the rate of signals
with the source is a factor 60.

See figures.

This hints to the origin of this component as due to an increased sensitivity
to gamma-rays (more  material?) or internal radioactivity (gamma,beta) 
of ORNL tubes.

Background measurement over night with CLOVER and VETO detectors

Start: 23:45
Stop: 10:56
File: 161012_1056_bck_noise.root

We see a very strong noise in the BRIKEN spectrum!!!
After some work we find that this was a problem
with configuration file: when editing the file
we put the calibration sheet at the beginning this
provoked a mixing of CLOVER and 3He spectra.

ROOT macro for calculation of neutron rates in the BRIKEN detector

Here a ROOT macro to calculate neutron rates from onlines root files generated DAQ configuration 
160718Conf_BrikenFull_cal5.xlsx (and the later ones).

Setup parameters are indicated at the begining of the macro. An output data file is generated with the rates by counter, ring and ADC. If the input root file is "file.root", the

We are using the calibration from July which
works surprisingly well for all except G7Red
(explains double peak in spectrum)

More checks to be done.

Optimization of ADC thresholds

In order to try to reduce the grass-like background
we make a finer adjustment of individual ADC thresholds.
We make first a control measurement putting the 252Cf source
in the center of the detector (AIDA removed)
Start: -
Stop: 23:55
File: 161009_2355_252Cf_control.root

We then make an adjustment of thresholds one ADC at a time.
We adjusted the threshold so that the very low amplitude noise height
in the spectrum is only a small fraction of the pulser.

New configuration file: 160718Conf_BrikenFull_test02_thr.xlsx

A verification measurement with 252Cf
Start: 01:55
Stop: 02:09

And the leave a background measurement overnight:
Start: 02:12
Stop: 07:12
File: 161010_0712_bck_newthr.root

We compare the grass-noise rates now with the rates before threshold adjustment
For that we integrate the BRIKEN spectrum between 900keV and 1.5MeV
The rate before was 0.085 counts per second per MeV
The rate now is 0.039 counts per second per MeV
So the improvement was only a factor 2.

One can try to set the thresholds higher  however with this rate the probability
of having a noise signal in a 0.5ms window after a beta signal will be about 1E-5.

The plots below show the situation before and after.

Due to maintenance operations of the Wako electrical
company there is a risk of power shutdowns on Saturday,
Sunday and Monday from about 8 am to 8 pm.

So we have to stop working on the hardware during
this time

We check for the appearance of spurious signals in the preamplifiers.

We set all HV to zero and run a measurement for several hours.
Start: October 7, 20:00
Stop: October 8, 06:42
File: 161008_0642_noHV.root

De inspection of the different channels do not reveal any
particular problem.

See figure for channels grouped in rings

We increased the pretrigger delay for ADC5 from 350 to 400

We investigate the effect on the noise in ORNL tubes of using a differential PA.

We connect the tubes in current PA10 (126-140) to one of the new diff PA
and connect the output to converter card #4 which is connected to ADC3 (and ADC4).

First a short run with 252Cf for setting the right parameters and the calibration
file: 161007_1743_252Cf_ORNL_diffPreamp.root

Then we make a background run
file: 161007_1743_bck_ORNL_diffPreamp.root

As can be seen in the figure the effect of the differential preamp is to
compress the noise down to 100keV, becoming more similar to
the situation of the RIKEN tubes.

Thus it will be beneficial to use Diff PA. However as we can only setup one
because we have only one spare Diff-Unip converter card, we decided not to
use it as the impact will be very low and implies a lot of changes.
However one must remember that since we are always going to require coincidence
with betas during the measurement this noise should have no effet.

Low amplitude noise component.

The figure shows the composition of the low amplitude noise
which depends on the tube and type of preamplifier used.

Bkack: He020 (RIKEN-Diff)
Red: He044 (UPC-Diff)
Green: He057 (UPC-Unip)
Blue: He068 (ORNL1-Unip)
Pink: He132 (ORNL2-Unip) 

(all the tubes of the same type and preamp type behave alike)

We can see up to three different structures.
The noise in the ORNL tubes extends to higher energies (200keV)
and are the cause for the overlap of noise with neutron signals,
but other wise the shape is similar to RIKEN tubes.
The noise for UPC above 50kev is quite small.
One can also see a small difference between differential and unipolar PA
in the case of UPC tubes (red and green)

Background measurement overnight
Start: Oct-6 2242 Stop: Oct-7 10:45

file: 161007_1045_bck.root

See attached figure.
We see that low amplitude noise overlaps with the neutron spectrum.
We also see the grass-like background which extends all the way
up to the ADC range.

First measurement with 252Cf source to check the calibration.
AIDA was in place so the source was at the right height

We use the last configuation file used in July: 
160718Conf_BrikenFull_cal5.xlsx

tmeas=25min

The noise is rather small.
The calibration of July is nearly OK!

We mount back all preamplifiers
Initially we used all the PA coming from US, the repaired and the new ones.
There was an issue with the new ones (strong noise and cross talk)
until we realized that the new ones were of differential type
instead of unipolar. We decided to mount all unipolar so we use
the repaired ones plus the ones which were left here and 
had some minor problems with discharges.

We decided to change slightly the gain of the pulser signals
because for PA6 to PA10 the amplitude after the preamp was 2.2-2.4V
so it was saturating the ADC.
So we decreased Pulser 1 (RIKEN, ORNL1, ORNL2, CLOVER) 
from 690mV to 540mV (NEG) on the scope (50ohm)
and increased Pulser 2 (UPC) from 90mV to 100mV

We started the assembly of BRIKEN and AIDA detectors in their final position
on Tuesday October 4:

Gabor Kiss, Phong Vi, Keishi Matsui, Shunji Nishimura, Shigeru Kubono, PA,
Chris Griffin, Tom Davinson, Nathan Brewster, Shintaro Go, Daniel Stracener,
Ariel Tarifeno, Jorge Agramunt, Alvaro Tolosa, Jose L Tain

Tubes were removed from BRIKEN. PE matrix lifted with crane.
Table rotated and placed in the final position (front wheels 
between forward EURICA rails) by hand. Table leveled (height, angle)
with the help of laser. PE matrix placed back.
AIDA rotated and adjusted to BRIKEN by hand.

Collaborators,

Attached is a phone photo of example signals from the new preamps with 3 3He tubes connected to a scope. Scope channels 1,2,3 (color y,c,m respectively) are preamp channels 1,2,3 while 4 (green) is open. Trigger is on channel 3, at 500mV/div and other channels are at 500,200,and 20 mV/Div for channels 2,1,4 respectively. Time scale, though glared out should be 10us per div ( although we saw longer rise times as well). 

Signals were all good for all channels. Coincident with real signals were other negative signals ~15x (750mV/50mV magenta/green) smaller and with a different shape. No positive signals were observed in any channel.

This picture is representative of the signals of 2 new preamps as well as the functional spare already at UT. 

Additionally, the two preamps sent for repair have been received.

 According to the reply from Japan Radioisotope Association, the accuracy of the Cf-252's intensity is +0%/-15%.

( "+0%" is important, because 3.7 MBq is a standard limit for radio-active sources  in Japan.)

There might have been a slight improvement on the PA behaviour
but is not clear.

Attached a screen shot of the spectrum

The spurious signals show very little noise superimposed
as can be seen in the attached capture of the sample by the DACQ
but is not so obvious how this can help to veto them.

Drying of preamplifiers

PA8, PA9 and PA10 are removed and brought to a dryer box
to stay overnight and see if the situation with spurious signals
improves as suggested by Mesytec.

Attached screenshots of raw data for every digitizer. 

The problem of some of the PA is visible in the background
spectra. 

In addition one can see in some of the channels signals
distributed over all the region up to the pulser and beyond.
This we found to be related to a too low threshold
but can be eliminated with a better adjustment.
